Na kraju utakmice rezultat je bio dva prema jedan za naš tim.

This means at the end of the match.

Grammatically:

• na kraju = at the end
• utakmice = genitive singular of utakmica = of the match

So the structure is literally at the end of the match.

A useful contrast:

• na kraju = at the end
• na kraj = to the end / to the edge, with a sense of movement

So in this sentence, kraju is used because it describes a location or point in time, not movement.

Because after kraj in this meaning, Croatian normally uses the genitive.

So:

• utakmica = the basic dictionary form
• utakmice = of the match

This is very common in Croatian:

• kraj filma = the end of the film
• početak sata = the beginning of the class
• sredina tjedna = the middle of the week

So na kraju utakmice follows a normal pattern.

Croatian does not have articles like the or a/an.

So rezultat can mean:

• a result
• the result
• in sports context, often the score

The exact meaning comes from context. Here, because the sentence is about a match, rezultat is naturally understood as the score.

Here it means score.

The word rezultat can mean either:

• a general result
• a sports score

In a sentence about a match, Croatian often uses rezultat where English would more naturally say score.

So:

• Rezultat je bio 2:1. = The score was 2:1.

Because this is the Croatian past tense.

A very common past-tense pattern is:

• present tense of biti = to be
• plus a past participle

Here:

• je = is/has as the auxiliary, 3rd person singular
• bio = past participle of biti

Together, je bio means was.

Also, bio agrees with rezultat, which is masculine singular:

• rezultat je bio = masculine singular
• if the subject were feminine, you would get bila
• if neuter, bilo

Yes. dva prema jedan is a normal way to say two to one.

In sports scores, Croatian often uses:

• X prema Y

So:

• dva prema jedan = two to one
• tri prema nula = three to nil
• jedan prema jedan = one to one

In writing, you will also very often see 2:1 instead of spelling it out.

Because in this kind of score expression, Croatian normally uses dva.

The difference is:

• dva = masculine/neuter form
• dvije = feminine form

When a feminine noun is explicitly stated, you often need dvije:

• dvije minute
• dvije utakmice

But in a bare score like dva prema jedan, the usual form is dva.

Here za means for or in favor of.

So:

• dva prema jedan za naš tim = two to one for our team

After za, Croatian uses the accusative.

That is why we get:

• naš tim

But because tim is a masculine inanimate noun, its accusative looks the same as its nominative:

• nominative: naš tim
• accusative: naš tim

If the noun were feminine, you would see a clearer change:

• za našu ekipu

Yes. A few common alternatives are:

• ekipa = team, squad, side
• momčad = team, especially in sports
• tim = team, also very common

So you could also say:

• za našu ekipu
• za našu momčad

All are natural. The choice is mostly about style and preference.

Yes. Croatian often shortens this kind of sentence if the context is clear.

For example:

• Na kraju je bilo dva prema jedan za naš tim.
• Utakmica je završila dva prema jedan za naš tim.
• Na kraju je bilo 2:1 za naš tim.

The original sentence is completely correct and clear; it just sounds a bit more explicit because it includes rezultat je bio.
